JSONDecodeError. after running "bench update && bench build "

Frappe Framework
,
1

I have been exploring the deployment of ERPNext on raspberry pi 5 on ubuntu server. I have successfully completed setting up production server later thought of adding Custome fields to the doctype and switched to development option but could not switch back to the production despite trying the options that i could find on forum and documentation. final command that i remember that i have executed is bench update and bench build, Since that I am struck at “internal server error” and “json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)” in my console. @frappedev @support1

bench build most likely didn’t succeed hence asset.json doesn’t exist.

Try rerunning it, my hunch is RPI is not capable enough for running frappe/erpnext and building it.

Thanks for replying @ankush. I am running erpnext on high spec RPi-5.

after running build command i am getting the following error

The above exception was the direct cause of the following exception:

I believe it is trying to fetch the files that are not present. i have pulled different branch and tried building but same result.
